METALLIC CROSS-TIE AND RAIL-FASTENING.

Specification of Letters Patent.

Application filed December 19, 1907. Serial No. 407,166.

To all whom it may concern:

Be it known that I,,WILLIAM J. Sroor, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Metallic Cross-Ties and Rail-Fastenings, of which the following is a specification.

One object of this invention is to provide a metallic tie of such form as to receive direct from the rails all of the lateral thrust, completely relieving -the rail fastenings of the thrust strains so that their only function is to hold down the rails.

A further feature of the invention is the rail fastening and the means applied in securing the fastening in rail-holding position.

While the invention is not confined to a tie formed by rolling, it is. my purpose to provide, and I have here shown, a tie section which may be readily rolled in blanks or beams of any desired length which are subsequently cut up into proper lengths for crossties.

In the accompanying drawings, Figure 1 is a top plan view of portions of a rail and tie embodying the invention. Fig. 2 is a view in side elevation of a portion of a tie, the rail being shown in section. Fig. 3 is a cross sectional view of the tie, taken through one of the fastenings, the rail being shown in elevation. Figs. 4 and 5 are detail views of the hook-bolt.

The metallic tie in and with which the in vention is'preferably embodied is of modified I-beam form, 2 designating the base thereof, 3 the web and 4 the top portion on which the track rails 5 rest.

The top 4 is rolled with longitudinal flanges 6 on its top face, the flanges being preferably located at the opposite longitudinal edges of the top. The flanges are interrupted at 7 to form passages for the rail base, the interruptions being only a trifle longer than the width of the rail base to afford an easy fit. The flanges correspond in depth to the thickness of the rail base at its outer edge to afford abutments or shoulders 8 the full depth of those edges. The depth of the flanges may vary with variations in thick ness of the rail bases, determined by the weight of the rails. V

The hook-bolts 9 extend downward through passages in top 4, with a vertical slot 10 in each bolt so located that its upper end is always above the under face 11 of top 4. 12 is a flat key having an oblique lower edge 13 which gives a wedging action when the key is entered in the bolt slot, said edge bearing on the lower extremity of the slot while the upper edge bears against face 11, thus holding the hook-bolt tightly in place.

The key has a horizontal slit 14 extending inward longitudinally from its smaller end,

so that after the key has been driven inward as far as desired portion 15 thereof below the slit is bent laterally and locks the key in position.

The hook-bolt is shouldered at 16 beneath the head to bear on the top face of the tie, the shoulder being preefrably formed on three sides of the bolt, there being no shoulder on the face next to the rail base. The shoulder is so located as to hold the hook-like-head in proper relation with the rail. In practice, it is desirable to have the head simply engage the rail without exerting any considerable clamping pressure thereon, so that the fastening is not endangered by the expansion and contraction of the rail. In fact, the arrangement may be such as to allow a perceptible clearance between the under face of the bolt head and the rail base.

Angle plates 17 may be secured to the op posite faces of web 3 and form wings which project laterally into the ballast and prevent the tie from walking.

The improved tie is of such shape that it may be rolled without difliculty, and after rolling it is only necessary to out the rolled beam into proper lengths. The rail passages through flanges 6 are readily formed with a coping or milling machine, and upon forming the bolt passages the ties are ready for use. It will be understood however, that the invention is not limited to the sectional shape here shown, nor to forming the tie and its flanges 6 by rolling.

The advantages will be apparent. The fastenings are completely protected from the side thrust of the rails, the latter being imparted directed to and resisted by abutments 8 of flanges 6, so that the only function of the fastenings is to hold down the rail. Flanges 6 materially strengthen and stiffen the tie. The formation of the slot and key locking means for the hook-bolts is such as to hold them with great security, the flat keys arranged edgewise being far in excess of any upward strain to which they may be subjected. To release the rails it is only necessary to straighten the laterally bent portions 15 of the keys.

the resistance of I claim 1. A metallic tie having a bolt opening through its top, a vertically slotted rail securing bolt extending downwardly through the opening and shouldered to bear on the top-surface of the tie when the bolt is drawn downward Without exerting pressure on the rail, the bolt being slotted ertically with a portion of the slot within the plane of the tie top, a wedge shaped key in the slotwedg'ing between the lower end face of the latter and the under face of the top portion of the tie, the key being split with the metal at one side of the split wedgi-ng against the tie as d'e scribed, and the meta'l'at the other side of the split turned laterally to hold the key against displacement.

2. A metallic tie having laterally separated flanges extending longitudinally thereof and projecting upwardly from its top surface, the flanges having interruptions corresponding in length to the width-of a rail base With the end walls-of the interruptions forming abutments for the opposite edges of the base, the tie having bolt passages located between the flanges, bolts headed at their upper ends to overhang the rail and shouldered beneath said headed ends to bear on the rail supporting surface of the tie, the bolts ex= tending downwardly through said bolt passages and slotted vertically with portions of the slots extending into the plane of said passages, and a tapered key wedging in eachslot between the lower end thereof and the under face of the to portion of the tie for holding the bolt shou der in tight engagement with I the rail supporting surface without clan'ipin g I the bolt head in tight engagement with the rail.

3. A metallic tie of I-beam form raised flanges at the longitudinal edges 01' its top face extending from end to end of the tie, the flanges being interrupted to receive and form lateral abutments for the rail, the top portion oithe tie having vertically slotted hook-bolts in the passages and shouldered to bear on the rail supporting surface, and a tapered key in the slot 01' each bolt Wedging between the top'portion ol the tie and the bottom I ace of the bolt slot with means for holding the ke in place.

4. A cross tie for railways substantially L shaped in cross see'tionaiul provided with interrupted ribs or beads along the edges or the ra'il-si'ipporting flange, said ribs or beads bein suitably spaced to form seats for the rail-"lange and hold the same from lateral movement in either direetion, the opposite flange being adapted to serve as an anchor and the web of the tie being in a plane at right angles to the plane of the flange of the rail supported by the tie;
